iVectorOne is a live search tool that connects to the supplier’s live booking systems, therefore iVectorOne doesn't pre-cache availability data. There's not an option to broad search to see availability at this level (e.g. a calendar / week view). You wouldn't know this information until you search.
If caching is a requirement, iVectorOne has a sister product, DealFinder, which is an enterprise-level caching tool to power flight+hotel and hotel-only web search tools.
